Create NAT Instances for Traffic Routed through a Layer 3
Switch or Router
To create a NAT instance for traffic routed through a Layer 3 switch or router,
follow these steps.
1. From the NAT tab, click New Instance to display the General tab of the
NAT Instance dialog box.
IMPORTANT Set up all Smartport roles and VLANs before creating NAT instances.
If you change a Smartport role or the native VLAN for a port associated with a
NAT instance, you must reassign VLANs to the NAT instance.
IMPORTANT As a result of Layer 2 forwarding, current traffic sessions remain established
until manually disconnected. If you change an existing translation, you must
manually disconnect all associated traffic sessions before the new translation
can take effect.
